The foundations of computer science and programming are based on the study of data structures and algorithms. In this article, I will give you an introduction to data structures and algorithms.
Data Structures and Algorithms
Data structures and algorithms are one of the most fundamental aspects of programming that should be taught in all courses related to computer science and programming. You can learn any programming language you like, but to be a good programmer you need to develop a mastery of data structures and algorithms.
What are Data Structures?
There are so many common data structures in every programming language like arrays, linked lists, stacks, queues, and trees, to name a few. The work of all data structures is to store a collection of values, but they differ in how they organize individual data items and by what operations can be applied to manage the collection.
The choice of a particular data structure depends on the ADT and the problem to be solved. Some data structures are better suited to particular problems. For example, the queue structure is perfect for implementing a print queue, while the binary tree is the best choice for a database index.
Whatever data structure we use to implement an ADT, by keeping the implementation separate from the definition, we can use an abstract data type in our program and later change to a different implementation, if needed, without having to modify our existing code.
What are Algorithms?
An algorithm is a sequence of clear and precise step-by-step instructions for solving a problem in a limited amount of time. The algorithms are executed by implementing the step-by-step instructions into a programming language that can be executed by a computer. This translation process is called programming.
Computer programs are built using a programming language to solve problems. While programming is an important part of computer science, but computer science is not the study of programming. Nor is it about learning a particular programming language. Instead, programming and programming languages are tools that we can use to solve problems.
So, a programming language is a tool for solving problems and algorithms are the step-by-step instructions you should follow while writing a program. You can learn Data Structures and algorithms using C++ programing language from here.
